How to detect first day of a month with Day.js
I am building a calendar component in React without using any library but Day.js.
I need to detect the first weekday of the month in order to leave a gap as shown in the picture. Otherwise the first day of every month has to be Sunday. How can I detect the first weekday of the given date?
Solution
Day.js has built in function to achieve this
dayjs().startOf("month").day()
This method returns current month's first week day as number.
0 = Sunday, 6 = Saturday
